Procedures that return a fxmapping containing the associations of fxmap whose keys are equal to, less than/less than or equal to/greater than/greater than or equal to k. Note that the result of fxsubmapping= contains at most one element.

Examples:

(fxmapping->alist
 (fxsubmapping= (fxmapping 0 'a 1 'b 2 'c 3 'd) 2))
 ⇒ ((2 . c))

(fxmapping->alist
 (fxsubmapping< (fxmapping 0 'a 1 'b 2 'c 3 'd) 2))
 ⇒ ((0 . a) (1 . b))

(fxmapping->alist
 (fxsubmapping>= (fxmapping 0 'a 1 'b 2 'c 3 'd) 2))
 ⇒ ((2 . c) (3 . d))
